Block of cool

ABSTRACT

A relatively fresh approach to the evaporative air conditioner industry of today. It uses solar power to convert used-up water that normally is evacuated by different means like bleeding off water from the hose of distribution assembly. It uses a three section water deposit, four submergible pumps and a solar panel and rechargable 12 volts battery.  
     One of the water deposits is used allways while the other two are used only at programed and timed intervals.  
     A delayed floater switch assembly is used to sense water presence at different sequences and do most of the timing.  
     Also a dual water check-valve is used to recieve water from two different pumps at different times.  
     The latest state of the electronics art is being used to accomplish the task of saving water usage and maintenace costs.

[0001] This application is entitle to the benefit-of provisional application Ser. No. 60/358,739.

BACKGROUND

[0002] 1. Field of Invention

[0003] This invention relates to evaporative air conditioners specifically to lower maintenance costs.

[0004] 2. Description of Prior Art

[0005] One example of such apparatus is the legendary “Bleed-Off Kit” This invention tries to keep mineral . . . salt concentrations . . . residues . . . etc. to a minimun by simply connecting a ¼″ hose from the water distribution assembly hose directly to the roof's sewer pipe.

[0006] This continuous water flow wastes water excessively: Some cities have prohibited this method due to the scarcety of drinking water reserves.

[0007] There is also a product in the market sold by most Cooler's distribution suppliers; (U.S. Pat. No. 5,527,157) This invention is nothing more than a water pump timed to evacuate cooler's deposit every 8 hours or so.

[0008] Another product named Mighty might distributed by Aspen-Snow works in about the same principal, except it drains all the water from coolers's deposit every time unit is turned off. All methods mentioned above have a thing in common . . . They all waste too much water in order to keep residues in check.

SUMMARY

[0009] The subject invention offers a fresh approach to lower maintenance costs and save water at the same time. We shall name it “Block of Cool”. (BOC for short)

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] While most evaporative coolers in use today employ a single large water deposit, BOC uses a three-section smaller one, two of those sections are in stand-by mode most of the time. Using a small amount of water pays off when it comes to evacuating used-up salinated water from deposit. Salt concentrations are contained and disposed off easier in a small mass of water. A large amount of water absorvs lots of solar heat during a summer day; Pads showered with a fresher water produce a much colder air flow and into the rooms.

[0011] When no provisions are taken, a layer of salt will adhere to pad surfaces. Corrossion will also result to sides and bottom of deposit. Pads will succum and become full of salt looking like a big chunk of white rock.

[0012] Some serviceman will recommend replacement of whole unit when confronted with a corroded deposit. BOC's three-section deposit can be removed easly to be refurbished or replaced with no hassle . . . No need to replace the entire cooler.

[0013] BOC is an improved version of evaporative air conditioner, unlike most it uses a small amount of water, enough to wet pad (media) and then it recycles used-up water to maintain salt and mineral residues in check. (instead of draining it to the roof's sewer pipe)

[0014] Briefly, the subject invention uses a three-section water deposit and four submergible water pumps. Each unit programed to do specific functions at different intervals in a sequencial manner.

[0015] Pump A (from deposit section A) showers pad initially, empting deposit A immediately. Deposit A recuperates its original water level(via a relay controlled water valve connected to its main water supply.) Section C employs two water pumps, (C-1 and C-2) pump C-1 helps pump A to completely wet pad and then shuts-off.

[0016] The water showering pad will start draining back to deposit A and since deposit A has reached its original level an overflow will result that will end-up into section B.

[0017] This over-flow is possible because the separation border dividing section A and B is lower than the rest of deposits perimeter. (gravity force at work)

[0018] Once deposit B gets full, a sensor switch will activate pump B sending entire overflow to solar pan. (FIG. 7 numeral 103) Vapor retainer (FIG. 5 numeral 101) Which is made of glass or a transparent material, will start converting water contained on solar pan into vapor. This vapor will form tiny droplets on underside of glass, droplets will gradually increase in size and slide to bottom edges of glass finally falling into collector. (FIG. 6 numeral 102) All this is possible thanks to the sun rays entering thru vapor retainer glass surface. Collector will then discharge its contents to deposit C. When the cooler is shut-off, pump C-2 will discharge its contents to pad, this shower of clean and distilled water will displace salt and mineral residues from pad's surfaces before pad becomes dry.

[0019] Under this conditions pad's usefull life-span is increased ten-fold. It is a well known fact that salt and mineral residues ruin pads. No residues . . . no harm is done to pad, water is saved, corrosion stops, labor is minimun and of course maintenance cost is reduced dramatically.
